LS2 or LS6

[White98TA]

is the GTO going to have the LS6 or the LS2? Sorry if this has already been asking and I was just wondering..............Anyone know for sure?

[Rick76]

I don't think anyone knows for sure but Holden will be using the LS2 as an LS1 replacement eventually so my guess is LS2.

[Big Als Z28]

they might use the remaining LS6 parts left over from z06's and make a small run of higher performance GTO's, but the CTSV might be eatting up the reserves. If its the LS2, It might not come till the 3rd and last year of Holden made GTO's.

i was informed its getting an ls2.usually when the vette motor changes any other v8 powered cars from GM get a similar motor.they usually change over a year later but this time ive heard otherwise.


it makes economic sense by lowering production costs.

[Decromin]

You see, while GM wants to put the LS2 in the Vette first, Holden is by far the biggest user of the LS1/LS2 motor. With the demise of the F-bods, GM needs the numbers seen from Holden to keep the motor viable ...

[Big Als Z28]

agreed. But thats if and only if Holden puts the LS2 into there cars next year. Remember, Holden doesnt follow the fbody rule of 1 year later.
Chances are that Holden will use a detuned version much like they have with the LS1. I belive its rated lower then what the fbody, vette and GTO get here. If the LS2 is put into Holdens next year, then yes the GTO will get the LS2.

[ULTIMTEORANGESS]

does GM run or own holden or decide what power trains go in those vehicles?i dont know too much about them but it doesnt make sense to put anything but a detuned ls2 in this car.

[Big Als Z28]

Holden is a offshoot of GM. They use an detuned LS1 in there Monaros and Commodores, but they do have higher performance HSV models that make some serious power. The LS1 in the GTO makes more power then the LS1 Monaros. Holden decides what they want to do, and up to about last year no one really cared about Holden. Not untill Lutz got an email from the top guy and invited him to come down to Holden did he realize what a fantastic group of cars they have.
I have a strong feeling that if the oil embargo and insurance rates didnt hit so hard in the US back in the 70's, that GM would look a lot like Holden.

[White98TA]

i think if they just put an Fbody LS1 in the GTO next year, it would probably run 12.8's bone stock and dominate everything.........

The LS2 will not be in the gto..

and you know this how?

why did an SLP employee tell me theyre doing the judge conversion and itll have this motor?


not saying thats conclusive proof but why would he lie to me?



theres other things that would lead me to think itll be in newer GTOs like saving on production costs instead making different variations of ls1s.

[Jeffro]

It might be in it for 2006 but I really doubt we'll see it before then. An LS6 is more likely to make an appearance in the GTO.

[GTOJ]

I would think that you would see the LS2 in the 2006 car or a high performance model next year. But not as standard equipment.

Logic. Vette gets it in 05, while 06 would be a possibility it would make for fiscal sense to keep with the LS1/6. Tooling cost are paid for, the LS2 would have to be detuned to mate with the A-4.

Not if Holden decides to use the Gen IV small block. News out of Melborne says that the Holdens will use the gen IV small block.
this is from ls1gto.

In todays' Melbourne Age (April 1 but I think this is fair dinkum) Holden's director of Sales and Marketing is quoted as saying the 6.0 litre LS2 is awaited for installation in the upgraded and slightly restyled next model, which will see the current chassis out. It will eventually replace the 5.7 litre Gen III within 12 months. It would not be practical to continue building it once the VE Commodore arrives in 2006.

The LS2 Monaro sports 'more than 250Kw (350hp) in standard guise'. Up until now, the car has been designed 'as a unique fashion statement for people who wanted to look good', but 'from here to the end of this car it has got to be about performance'.

'Holden design boss Mike Simcoe said the next Monaro - the design has already been signed off on - is being engineered to take a convertible if a market can be found'.

Reading between the lines, the new car will have 350+hp as a Monaro, possibly with more low-end power (a complaint here of the Gen III compared to the Ford quad-cam 32-valve 5.4) to leave some tuning room for HSV and probably 400 as a GTO.

The '05 will only be touched up. The big changes will happen during '06 - smart move not to wait for '05 IMO. I suspect the next chassis will be slightly smaller, lighter and sportier and possibly aimed fairly and squarely at outperforming both Euro V8 coupes and quasi-musclecars like Mustang variants, but that's my read only. They will fix the trunk/fueltank problem, engineer it for anyhand-drive, ragtop and better weight distribution.

The Holden Omega-platform was engineered for bigger cars, including commercials and stretched versions (Ute, Wagon, Caprice) - now they have the option to re-engineer to allow for a shorter sports chassis.



and the 4l65E is used in the Vette to handle the power. Not to mention the torque management system thats on the A4 GTO's now.

Yea, I agree if Holden made the change then it would make sense, but just to do the gto and not the holden :dunno:

Consider this:

The GTO uses a different grind camshaft than the Holdens.

The engines are shipped (relatively) complete to Australia.

The GTO rolls down the line mixed with the Monaro.

The factory already is set up to pick from different "bins" of engines depending on the next car on the assembly line, making sure the different configuration engines are going with the right car. (they may do this by doing "runs" of several types of cars at the time but nevertheless, they can mix engines on the same line.)

Externally, the Gen IV block is supposed to be very similar to the Gen III block so there shouldn't be too many structural changes to use the new engine if any at all.

Holden could, theoretically, use the Gen IV block and Gen III block on the same assembly line.

The GTO could end up with the LS1/LS6 engine even if the Holden's get the LS2.

[White98TA]

sweet, my thread has extended to TWO PAGES!!!!!!!!!!!!!!!!!!!



woo hoo!!! :rotfl:

[Big Als Z28]

well this is how I see it
If the LS2 is used in the Monaro, the GTO will get it
if the LS1's are used again, the LS6 parts might be used if GM makes a "judge" or GXP model.

[Jeffro]

Another thing to consider is that the Caddy CTS-V is the only gm car to use the LS6 once the C5 is done. They will either start using the LS6 on another platform or they will drop it for another engine.

[20hawk02]

I'm hoping for the LS2. I better start saving up now just in case.

[Dwarf Killer]

I believe they'll definitely go with the LS2 in the GTO. It wouldn't make any economic sense to keep building the LS1 or LS6. GM always goes with the mass market to lower costs. The GTO will likely have a detuned LS2 engine (smaller cam, manifold etc.).

GM may only use the LS2 in the Corvette for the first year to iron out bugs, but again, I believe the cost of continuing production of the LS1/6 would be financially impractical.

They may run it out for one year after the LS2 is on the streets so they burn up existing inventory. It's not uncommon for GM to do that. They did it with the TPI and LT1 engines.

GM has very little into what engine goes into the car. If holden goes with gen IV's next year, then the GTO will get the Gen IV 6.0 LS2. What GM NA does when it gets here is up to them. Chances are a detuned cam. I would like to see "389" hp to hark back to the old 389 ci that started it all.
If Holden stays with the gen III production and keeps importing them, then I see GM using up LS6 parts between the CTS and GTO, but the LS6 equiped GTO will be a small number. Probably around 4k GTO's next year will get the LS6 if thats the case.
I also have a huge feeling that as soon as the C5 goes away, the 400hp of teh LS2 will morph into 410-425hp. I find it impossible that the LS2 makes 5hp less then the smaller, lower compression, lesser flowing manifolds intake and heads, and slightly larger cam. If it makes 400hp, GM has that puppy leaned out. Little PCM work, we could see massive power upgrades.

wow, this is interesting. I'm hoping for the LS2 also, but as with GM, "I'll believe it when I see it."
